    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 x/ lW=EQ  
    p=V (_  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: lZ'-?xo  
    enableservice('AutomationServer', true) E80C0Q+V  
    enableservice('AutomationServer') %s6|w=.1  
    G$<FQDvs  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 :%~+&qS  
    dnSjXyjFB  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 3FR'N%+  
    1. 在FRED脚本编辑界面找到参考. POdk0CuX  
    2. 找到Matlab Automation Server Type Library HNu/b)-Rb  
    3. 将名字改为MLAPP 8HS1^\~(6l  
    K\v1o  
    e/'d0Gb-  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 7;ZSeQ yC

    现在将脚本代码公布如下,此脚本执行如下几个步骤: X!KjRP\\  
    1. 创建Matlab服务器。 a=>PGriL  
    2. 移动探测面对于前一聚焦面的位置。 epqX2`!V  
    3. 在探测面追迹光线 v,#*%Gn`%  
    4. 在探测面计算照度 +ffs{g{  
    5. 使用PutWorkspaceData发送照度数据到Matlab rZm|7A)i  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?aR)dQ  
    7. 用Matlab画出照度数据 96x0'IsaG  
    8. 在Matlab计算照度平均值 GdVq+,Ge
